by unemployed workers demanding unemployment insurance were occurring
in virtually every major U.S. city. In New York, police attacked a crowd
of 35,000. In Cleveland, 10,000 people battled police. In Detroit, a
Communist Party organized unemployment demonstration brought out more
than 50,000. Thousands took to the streets in Toledo, Flint and Pontiac.

Activities Committee (HUAC), sponsored by Republican congressman
Hamilton Fish, with the support of the American Federation of Labor
(AFL), to investigate and quash radical activities. (From the Daily Bleed)

March 6, 1978 -
President Jimmy Carter invoked the Taft-Hartley law to quash the
1977-78 national contract strike by the United Mine Workers of America
(UMWA). The UMWA had been striking since December 1977, but rejected a
tentative contract agreement in early March 1978. Carter invoked the
national emergency provision of Taft-Hartley and strikers were ordered
back to work, but they ignored the order and the government did little
to enforce it. Eventually a settlement was reached and ratified in late
March. (From Workday Minnesota)
